Aviation Gasket Sealant

[UKPhilTR7]

To tell you the truth Has been I have not had the pump off yet to check it. I was thinking of taking it off and having a look but not checked for cracks or the diaphragm. I must admit that I still ling the idea of the electric upgrade and too true Beans, the extra wire would be a good winter project. I have been looking all around but I must admit that this one is catching my eye:

You'll need a good quality pressure regulator with these. Don't ask me why I know
And a good size filter between pump and tank won't harm either.

But better follow Russ' advice in your other thread. This choice is overkill for a standard engine.
And it looks like a cheap copy of the original Facet pumps.

Phil,
Concur Theo's latest advice (overkill). See comments on your other 'fuel pump' post. Rgds, DM

Is the aviation gasket sealant ethanol proof? supercass

Here's the link for the technical data sheet: https://www.permatex.com/wp-content/uploads/tech_docs/tds/80019.pdf
I gather that you're concern is with the fuel/ethanol blends.
I doubt that the smaller percentages of say 10% used in the typical blend won't have any appreciable effect on the gasket sealant but I would be wary of using it on high percentage mixes or straight ethanol.
